Approach Speed Calculator Pro vs Pressurisation

Good morning, Captain. Join over 6,000 pilots who use this tool to brief the approach speed for every landing, even in gusty, challenging conditions. Set the runway and the wind with one finger on the compass, set your VREF, and the approach speed is there. No mental math, no typing. BUILT ON THE BOEING METHOD The wind additive follows the Boeing Flight Crew Training Manual (FCTM): half of the steady headwind component plus the full gust increment, never less than VREF + 5 and never more than the limit you choose, VREF + 15 or VREF + 20. With a tailwind only VREF + 5 applies. It applies from the 727 to the 787, and the same method is in use on Airbus and other jets. WHAT YOU SEE • Approach speed, with the additive shown as VREF + n • Headwind or tailwind component and crosswind component, each with its gust • Colors that speak: green inside normal values, yellow for caution, red beyond limits • A warning when the approach speed gets close to your full flaps limit speed • Descent rate for a 3 degree path • Ground speed on final • Reference stall speed MADE FOR THE FLIGHT DECK • A compass you drag: outer ring for the wind, center for the runway. Fine tune degree by degree with the buttons • Dark instrument display, easy to read by day and by night • iPhone and iPad, with landscape on iPad • Knots and feet per minute, or meters per second • Works offline.

Transform Your Flight Experience with Advanced Cabin Monitoring Cabin Pressurisation is your companion for understanding and visualising how aircraft cabins are pressurised at altitude. Whether for training, education, or curiosity, this app brings complex systems to life with authentic cockpit-style instruments and intuitive displays. Cockpit Modes (Tailored to Aircraft Types): Advanced EFIS – State-of-the-art display (max 9.0 ΔP) Turboprop – For smaller turboprop aircraft (max 5.5 ΔP) Corporate Jet 8.6 PSI – Inspired by a renowned business jet (max 8.9 ΔP) Corporate Jet 10 PSI – Modelled after the fastest business jet (max 9.6 ΔP) Airliner Legacy – Classic jet airliner design (max 9.1 ΔP) Airliner EFIS – Modern jetliner interface (max 8.6 ΔP) Key Features: Cabin Altitude Gauge (CABIN ALT) – Displays cabin altitude in thousands of feet. Differential Pressure Gauge (ΔP) – Shows the pressure difference between cabin and outside air. Variometer (CABIN CLIMB) – Tracks the rate of cabin altitude change. Ground Speed Display – Monitors ground speed in knots. Limitations: GPS Dependent – Best performance when your device is near a window. Mach Indicator – Approximate only (based on ground speed and altitude). Important: This app is designed for educational purposes only. It is not a substitute for certified aircraft systems or instruments.
